Description of the invention: [Technical field to which the invention pertains] 曰 The present invention relates to a heat dissipation module, and more particularly to a heat dissipation module capable of effectively improving heat dissipation efficiency. [Prior Art] As the performance of the electronic device is improved, the heat dissipation capability of the heat dissipation structure of the electronic device needs to be simultaneously increased to effectively dissipate a large amount of heat energy generated by the heat generating component. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a schematic view showing a heat sink 100 mounted on a heat-generating electronic component (not shown). The heat sink 10 includes a heat sink 102 and an axial fan 104. When the heat sink 1 〇 2 absorbs heat generated by the heat generating component by heat conduction, the airflow generated by the axial fan 1 〇 4 can be The heat absorbed by the heat sink 102 is dissipated. However, as shown in Fig. 1, the conventional fan and the heat sink are arranged in such a manner that the air flow caused by the fan 104 is air generated by the adjacent heat sink 1〇2, so that the air temperature of the fan just blown into the hot air is about the high temperature. Therefore, the surface temperature of the heat source (heated electronic component) (for example, a central processing benefit surface of about 65-7 (TC) differs from the cooling air temperature by only about 25 ° C, which greatly limits the heat transfer efficiency. Furthermore, it is limited by The design of the wind turbine motor, the heat corresponding to the horse's income; the length of the 1〇2 towel point: the smallest amount, but here is the place where the heat source is the most concentrated and the temperature is the highest, which not only reduces the heat transfer rate but also easily leads to SUMMARY OF THE INVENTION Accordingly, the object of the present invention is to provide a heat dissipation module that can effectively solve the above problems of the prior art. The heat dissipation module according to the present invention includes an air delivery system. The device and a heat dissipation chamber having an air inlet and an air outlet. A heat transfer enhancement structure is formed on the inner wall surface of the heat dissipation chamber, and an outer wall surface of the heat dissipation chamber is attached to a heat generating component. The air conveying device causes airflow into and out of the heat dissipation chamber. It can use an air compressor, a blower or an air pump, and the heat transfer enhancement structure is formed into a flow of air inside the heat dissipation chamber. One of the flow passages. The heat dissipation chamber can be formed by a plate member and a heat sink. The heat transfer enhancement structure formed by the surface of the heat sink is shaped and positioned in advance with the through hole of the plate member. The position forms a continuous and feasible air flow path through each part of the heat dissipation cavity, so that when the compressor injects high pressure gas into the heat dissipation chamber through the through hole, the low temperature cooling air from the compressor can be pre-processed in the heat dissipation chamber The flow channel is fully contacted with the fins and finally discharged by an exhaust port. On the one hand, the low-temperature cooling air can be in full contact with various parts of the surface of the heat sink and the heat transfer enhancement structure on the surface of the heat sink. Therefore, any part of the heat sink has a large amount of low-temperature air flowing through it, and the heat can be uniformly carried away. There is no problem that the heat source of the conventional heat sink is the most concentrated and the temperature at the center of the highest temperature is 1287700. On the other hand, because the temperature of the cryogenic cooling air that is continuously supplemented is extremely different from the surface temperature of the heat sink, it can effectively increase the heat that can be removed by the air and greatly increase the dispersion. [Embodiment] Fig. 2 is a schematic diagram showing the design principle of the heat dissipation module of the present invention according to an embodiment of the present invention. As shown in Fig. 2, the heat dissipation module according to this embodiment is mainly composed of an air. An air compressor 10 and a pre-designed heat dissipating member 12. The air compressor 10 and the heat dissipating member 12 are connected by a gas-tight pipe, and the air is compressed by the compressor 10 in the direction indicated by the arrow, and is composed of a heat dissipating member. One of the air inlets enters the high speed and is discharged by an exhaust port, and a pressure controller 30 can be disposed on the airtight line to adjust the air pressure and the air flow. According to the embodiment, the heat dissipating member 12 is A plate member 14 and a heat sink 16 are formed in close contact with each other. The heat sink 16 is made of a material having a high heat transfer coefficient, and its bottom surface is attached to a heat generating component 28. 3A and 3B show an example of the design of the plate member 14 of the present invention. A through hole 18 is formed in the center of the plate member 14, and one or a plurality of fixing holes 20 are provided at the edge. 4A and 4B show an example of the design of the heat sink 16 of the present invention. As shown in the figure, a heat transfer enhancement structure is formed on the surface of the heat sink 16. According to the embodiment, the 1287700 heat transfer enhancement structure has the same height H from each part. The fin U is wound to form a winding form of the (four) sheet 22 such as counterclockwise winding or clockwise winding. The edge of the heat sink 16 is also provided with a plurality of side holes 24. Therefore, by using a fixing member such as a screw, the plate-like member 14 is locked with the heat sink via the fixing holes 2G and 24 which are mutually corresponding to each other, and the plate-like member 14 can be tightly covered over the heat sink 16 to make the two members A closed heat dissipation chamber having an air inlet (i.e., a through hole 18 in the plate member 14) and an exhaust port (the last outlet 26 of the passage in which the fin 22 is wound) is formed in the middle. Since the wound fins 22 of the present invention have the same height H, and when the plate member 14 is tightly covered over the heat sink 16, the top surface of the fins 22 may face the surface of the heat sink 16 with the plate member 14 19 is in close contact, so that when the air compressor is filled into the heat dissipation chamber through the through hole 18 in the plate member, the fin 22 originally serving as the heat transfer enhancement structure simultaneously flows into the interior of the heat dissipation chamber. The flow path, at this time, the airflow will follow the direction of the arrow b of Fig. 4, and the channel formed by the winding of the fin 22 from the point P will rapidly flow through the closed portion of the heat dissipation chamber, and finally discharged from the channel outlet 26. . With the design of the present invention, the slab formed on the surface of the heat sink 16 is shaped and positioned in advance with the passage of the plate member 14 overlying it, forming a continuous and feasible air through the various portions of the heat dissipation cavity. a flow path, such that when the compressor 10 injects high-pressure gas into the heat-dissipating chamber through the through-hole 18, the low-temperature cooling air continued by the compressor 10 can follow the preset flow path and fins of the heat-dissipating chamber 1287700 After partial contact, it is finally discharged by an exhaust port. In this way, the low-temperature cooling air can be in full contact with each part of the surface of the heat sink 16 and the heat transfer enhancement structure on the surface of the heat sink 16, so that any part of the heat dissipation chamber has a large amount of low-temperature air flowing, and can be uniformly Carrying away the heat, there is no problem that the heat source of the heat sink is the most concentrated and the temperature at the center of the highest temperature is the smallest. On the other hand, the temperature of the cryogenic cooling air that is continuously replenished is extremely different from the surface temperature of the heat sink 16, so that the amount of heat that can be removed by the air is greatly increased, and the heat dissipation efficiency can be greatly improved. Further, the number and arrangement of the through holes 18 of the plate-like member 14 according to the present invention are not limited at all. For example, as shown in Fig. 3C, a plurality of through holes arranged in an array may be formed on the plate member 14. Figure 5 is a schematic view showing the surface in which the plate member 14 and the heat sink 16 will be in intimate contact, respectively, to illustrate another manner in which the plate member 14 of the present invention and the heat sink 16 are combined. As shown in Fig. 5, the plate member 14 faces one surface 19 of the heat sink 16, and a winding bump structure 21 corresponding to the gap distribution between the walls of the fins 22 can be additionally formed. Thus, when the plate member 14 is combined with the heat sink 16, the bump structure 21 can be tightly embedded between the two walls of the fin 22 to closely cover the air flow path, and the plate member 14 and the heat sink 16 can be further obtained. The exact alignment and sealing effect of the two. Furthermore, in order to obtain the above-described precise alignment and sealing effect, 1287700 is not limited to use the above-described bump structure 21. As shown in FIG. 6 , on the surface 19 of the plate-shaped member 14 facing the heat sink 16 , corresponding to the gap distribution between the two walls of the winding fin 22 , a gate-shaped closed fin thin wall 23 is formed. The fins 22 on the heat sink 16 are fitted to cover the entire air flow path. That is, only when the plate member 14 faces the surface 19 of the heat sink 16 to form a fitting structure complementary to the heat transfer enhancing structure distribution pattern, the combination of the plate member 14 and the heat sink 16 can be obtained. Precise alignment and sealing effect. As shown in FIG. 7, the air compressor 10 of the present embodiment can also be replaced by a high-efficiency blower 32. The outlet of the blower 32 is connected to the heat dissipating member 12 by a gas-tight pipe, and the low-temperature cooling air can also be transported to The effect of the flow in the closed cooling chamber following the preset flow path. Moreover, the through hole 18 formed in the flat member 14 of the embodiment only needs to be designed with a preset flow path, and the outer shape and the opening area are not limited. Figure 8 is a schematic view showing another embodiment of the present invention. In this embodiment, an air pump 34 is used in place of the air compressor, and the air pump 34 is connected to the air outlet duct 26 by a fin line. The air pump 34 can be, for example, A vacuum pump. The design principle utilizes the air pump 34 to draw the air in the heat dissipation chamber to a negative pressure state. At this time, since the external air is higher than the pressure in the heat dissipation chamber, the air can quickly enter the heat dissipation chamber through the air inlet hole. The flow path is cooled to achieve the same effect of the present invention. 1287700 In this embodiment, the air inlet hole on the plate member 14 is preferably designed as a nozzle hole 18' whose cross-sectional area is tapered from the outside toward the heat dissipation cavity, so that when the air enters the heat dissipation chamber, the nozzle hole The cross section of 18' is gradually reduced to increase the air flow rate, so that the fluid itself can be converted into fluid kinetic energy, so the temperature of the air passing through the nozzle hole 18' is further reduced, further improving the heat transfer efficiency. Of course, the form of the air inlet hole on the plate member 14 is not limited. For example, as shown in Fig. 9, it may be in the form of a nozzle hole 18'' which is tapered from the outside into the heat dissipation cavity. Φ The heat transfer enhancement structure formed on the surface of the heat sink of the present invention is not limited to a fin structure at all, but only needs to be configured such that when the plate member 14 is tightly covered over the heat sink 16 to form a closed chamber, Forming a gas flow in the closed chamber can sufficiently contact the flow passages of the respective portions of the closed chamber. For example, as shown in FIG. 10, a large number of tiny bumps 40 may be formed on the surface of the heat sink 36 as a heat transfer enhancement structure for increasing the heat dissipation area, and the bumps 40 are simultaneously arranged to allow the airflow to be sufficiently closed. The flow channel of each part of the chamber can follow the flow path in the direction of the arrow when the air enters through the air inlet hole 38, and then is discharged by a plurality of exhaust ports, thereby improving the heat dissipation effect. Furthermore, the number and position of the air inlet holes of the present invention can be arbitrarily selected, and only the heat transfer enhancement structure is required to design the corresponding flow path. For example, as shown in Fig. 11, the design of the plurality of intake holes 48a and 48b may be employed, and the fins 42a and 42b may be formed into different flow paths corresponding to the respective intake holes. 11 1287700 It can be seen that the present invention provides the following advantages: if the various regions of the heating element have different heat dissipation requirements, the present invention can utilize the number of intake holes, the position and the corresponding flow channel configuration to be arbitrarily selected. Needle • Optimized flow path design for heat dissipation requirements in different areas. _ "The exemplified plate member 14 is only used to provide a through hole, and as a cover for the heat sink 16 to form a closed cavity, the shape is not limited.
